The 2wd'ers keep banging on about the Scoob losing 40% of its flywheel power thru 4wd losses - has anyone come up with a solution for reducing this? Seems like an 'easy' way of increasing power if its possible?? Switchable 2wd would certainly up the mpg on motorway cruising without compromising its 4wd abilities?

This has probably been done to death but I am relatively new around here so please humour me!?

Steve.

sounds like a plan, I seem to remember reading something somewhere (in the manual ?) about a 2wd/4wd fuse that could be used to dissable 4wd for towing etc. Not sure if if would save much power as would still have some friction losses via the diff etc, but should still be less that the engine putting power through the diff perhaps

Anyone else come across this fuse thingy??

 

I think the fuse is only on non-turbo Scoobs.

 

I'm pretty sure the fuse is only on autos............

 

I think your right, now I think about it. Shame..
Out of interest my LR Discovery was permanent 4wd whereas my earlier Shogun was selectable 2wd/4wd. Perhaps the losses are'nt that big and LR take the line of simplicity/cost versus saving in power/fuel ?
Interesting one, I'd be interested to see some actual %figures in losses..

 

You could fit straight cut gears throughout instead of helical cut, but it'd be noisy. My old Mini with S/C gearbox used to whine worse than the Missus, but it freed about 5% if I remember correctly.

 

Ooops
